which of the following phenomena applies the first law of motion
Answers
Newton's first law asserts that unless driven to alter its condition by an external force, every object will stay at rest or in uniform motion along a straight line. This is the most common definition of inertia.
Explanation:
The resistance of any physical object to any change in velocity is known as inertia. Changes in the object's speed or direction of motion are included. The tendency of things to continue travelling in a straight path at a steady speed when no forces occur on them is one example of this feature.
The word inertia is derived from the Latin word iners, which means idle or slow. Mass, which is a quantitative feature of physical systems, manifests itself in inertia as one of its major expressions. Before writing his first law in the mammoth Philosophi Naturalis Principia Mathematica, Isaac Newton described inertia as a force. There's a line that says:
Answer:
1. Newton’s 1st law a body remains in the state of rest or uniform motion in a straight line unless and until an external force acts on it.
2. Newton’s 1st law of motion in simple words, a body will not start moving until and unless an external force acts on it. Once it is set in motion, it will not stop or change its velocity until and unless some force acts upon it once more. The first law of motion is sometimes also known as the law of inertia.
There are two conditions on which the 1st law of motion is dependent:
1. Objects at rest: When an object is at rest velocity (v= 0) and acceleration (a = 0) are zero. Therefore, the object continues to be at rest.
2. Objects in motion: When an object is in motion, velocity is not equal to zero (v ≠ 0) while acceleration (a = 0) is equal to zero. Therefore, the object will continue to be in motion with constant velocity and in the same direction.
